Short to Ground:

4. Set the VOM to measure resistance. Connect the positive (+)

test lead to the case housing of the BCR. Connect the negative
(-)  test  lead  to  an  outer  terminal.  INFINITY  should  be  mea-
sured. Now connect the negative test lead to the BCR center
terminal.  INFINITY  should  be  measured.  Next,  connect  the
negative test lead to the remaining outer BCR terminal. Once
again INFINITY should be measured.

RESULTS:
1. If  any  of  the  previous  steps  has  failed,  replace  the  Battery

Charge Rectifier.

2. If the BCR tests good, refer back to the flow chart.

PROCEDURE:
1. Set a voltmeter to measure resistance.

2. Locate the 10 Amp circuit breaker (CB1) in the control panel.

See Page 17 for Circuit breaker location.

3. Disconnect Wire 15A and Wire 13A from the circuit breaker.

4.  Connect  one  meter  test  lead  to  one  terminal  of  the  circuit

breaker.  Connect  the  other  meter  test  lead  to  the  remaining
terminal on the circuit breaker. Continuity should be measured.
See Figure 6-26.

RESULTS:
1. If continuity was measured the breaker is good refer back to the

flow chart.

2.  If  INFINITY  or  a  open  condition  was  measured  replace  the

circuit breaker.

PROCEDURE:
Push in on fuse holder cap and turn counterclockwise. 

Then, remove the cap with fuse. Inspect the Fuse.

RESULTS:
If  the  Fuse  element  has  melted  open,  replace  the 

Fuse with an identical size fuse. If Fuse is good, refer 

back to flow chart.

PROCEDURE:
1. Inspect  the  battery  cables  and  battery  posts  or  terminals  for

corrosion or tightness. Measure the voltage at the terminal of
the Starter Contactor and verify 11-12 volts DC is available to
the generator during cranking. If voltage is below 11 volts DC,
